Your colon is the last part of your digestive system, where water and salt are removed, leaving solid waste before elimination. Sigmoidoscopy is a diagnostic and screening procedure to look at the lower parts of the colon. It is performed, with a slender, flexible lit tube called a sigmoidoscope, which is inserted into the rectum and guided into the colon. A fiberoptic camera on the scope enables your doctor to look at the lining for ulcers, abnormal growths, inflammation, and bleeding from the rectum up to the descending colon. Sigmoidoscopy is used to screen for polyps and early signs of colon cancer and to find the cause of problems such as diarrhea and abdominal pain. Polyps and tissue samples can be removed with instruments inserted in the scope.
